© 2017 Elsevier Ltd Humans, like many other species, employ three fundamental forms of strategies to navigate: allocentric, egocentric, and beacon. Here, we review each of these different forms of navigation with a particular focus on how our high-resolution visual system contributes to their unique properties. We also consider how we might employ allocentric and egocentric representations, in particular, across different spatial dimensions, such as 1-D versus 2-D. Our high acuity visual system also leads to important considerations regarding the scale of space we are navigating (e.g. smaller, room-sized ‘vista’ spaces or larger city-sized ‘environmental’ spaces). We conclude that a hallmark of human spatial navigation is our ability to employ these representations systems in a parallel and flexible manner, which differ both as a function of dimension and spatial scale.
